Component:  mythtv                              |     Version:  head

 The following patch makes several small improvements to the channel-
 scanning process for ATSC and MPEG-only (no SI data) scans:
  * Allow callsign and service name to differ.
  * For transports without inband SI data (e.g. many US cable-TV
 providers):
    * Avoid adding channels for which at least one of the following is
 true:
      1. We cannot find the PMT.
      2. We want FTA channels only, but the channel appears to be
 encrypted.
      3. The video stream contains the still-picture flag (e.g. it's a
 Music Choice^(R)^ channel); Myth currently does not play these streams
 correctly.
    * Don't overwrite known callsign and service name when updating an
 existing channel. In the absense of SI data this information must have
 been entered by hand and should not be overwritten by subsequent scans.
  * For transports with ATSC PSIP data:
    * If the VCT entry for a given channel includes an Extended Channel
 Name Descriptor, use the Extended Channel Name as the service name rather
 than duplicating the callsign. Otherwise use the Short Channel Name (which
 is used as the callsign) as was done before.
